Farrah Fawcett was in line for the role of Gloria. The studio opted for Goldie Hawn when Spelling-Goldberg Productions, the producers of Drôles de dames (1976), warned all the studios that "they would be sued for damages if they employed me," Fawcett told The Associated Press in 1979. She was still under contract with Spelling-Goldberg when she left the show. Fawcett is visible in the background at the party scene where Hawn's character is introduced.
This film is considered Dudley Moore's American film debut, and its success kick-started his American movie career. However, his first film seen in America was Fantasmes (1967).
The film is an homage to the suspense movies of Alfred Hitchcock. It was released seven months after Mel Brooks' Hitchcock spoof Le Grand Frisson (1977). Writer and director Colin Higgins previously wrote Transamerica Express (1976), another Hitchcock-like spoof thriller.
This was one of the ten highest-grossing American films of 1978. It was Goldie Hawn's first hit movie since Shampoo (1975). Its success enabled Hawn to get La bidasse (1980) made.
The movie's theme song "Ready to Take a Chance Again" was a hit, stayed on the American charts for 16 weeks, and even garnered a Best Song Academy Award nomination. It was sung by Barry Manilow, who also conceived and oversaw its production alongside of Ron Dante. Manilow had another song on the film's soundtrack as well, "Copacabana", which was from Manilow's fourth studio album "Even Now".
